Rationalizer
Rationalizer is a concept system for helping home investors to avoid making decisions based on emotion by using biofeedback. It consists of a bracelet which measures the arousal component of the user's emotion and a 'bowl' which displays a dynamic pattern of lights reflecting the emotion level measured by the bracelet. The bracelet can also provide feedback on its own through similar light patterns. The intention is that users can see when they are about to take actions based on strong emotions and can use this as a cue to reconsider.
